use in connection with cars, and it .is an object of the invention to provide a novel and improved door of this general character comprising a plurality of hingedly connected sections which may be readily assembled inoperative position, and whereby certain of said sections are capable of independent adjustment in accordance with the necessities of practice. I

It is also an object of the invention to provide anovel and improved door ofthis general character whereby the samemay be moved to one side of the opening. with which it coacts, or whereby the door may be maintained in an elevated position when not in use.

The invention consists 1n the details of construction and in the combination andarrangement of the several parts of my improved door whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that mv invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein .Figure 1 isa fragmentary view in elevation of the exterior of a car showing a door constructed in accordance with an embodiment of my invention in applied position; Fig. 2 is an elevational view of the inner face of my improved door as herein included, portionsof the car being indicated in section; Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1; 1

Fig. 1 is a detail vertical sectional view illustrating my improved door in a position atone side of the door opening; Fig. 5 is an enlarged fragmentary view partly in section and partly in elevation of a vertical edge of the door opening and illustrating certain details of my invention as herein embodied; Fig. 6 is a sectional view taken substantially on the line 6-6 of Fig. 5; Fig. 7 is an enlarged sectional View taken substantially on the line 77 of Fig. 1; and Fig.

8 is a fragmentary view illustrating in elevation the suspending member for the door as herein embodied, said member being shown in extended adjustment.

As disclosed in the accompanying drawings, Wdenotes the side wall of a car body having produced therein a conventional doorway or opening D and secured to the interior face of the side of the car body W above the doorway D and extending a liedetermined distance beyond a side thereof, is

a longitudinally disposed guide rod 1, sup

ported'in any desired manner, but preferably through the medium of the bearings 2,

projecting inwardly from the side of the car.

Mounted for sliding movement longitudi; nally of the rod 1 is the supporting member M herein disclosed as comprising an upper section 3 having its end portions provided with the upstanding barrels 4 through which the rod 1 is directed, and whereby said supporting member M is slidably engaged with the rod 1. The ends of the section 3are also pivotally engaged, as at 5, with the end portions of the intermediate section 6 which, when the door is in applied positionwithin the doorway or opening D, is adapted to linderlie the upper edge or wall of. said doorway or opening D, as is particularly illustrated in Fig. 3. The opposite ends of the section 6 are also pivotally engaged, as at 7, with the depending straps 8 which are of such a length as to overlie the outer face of the intermediate section A of the door proper, and as isparticularly illustrated in Fig. 1, it is to be observed that the lower end portions of the straps 8 are provided with the longitudinally directed slots 9, through which the clamping members of conventional form are disposed, said clamping members being carried by the intermediate section A, whereby it will be perceived that a vertical adjustment of the door proper v A and B are hingedly connected, as at 11,

in such a manner as to permit the lower door section B to swing outwardly which a is especially desirable when the car is to be unloaded, and in order to maintain the lower door section B in its elevated position, I find it of advantage to 'pivotally secure, as at 12, to the outer face of the intermediate door section A, the hook member 14 adapted to coact with the eye member 15 projecting outwardy from the lower door section B, and furthermore I find it of advantage to provide the outer face of the lower door section B with the hand grasp .16, whereby the lower door section B may be readily manipulated in accordance with the requirements of practice.

The upper door section C is hingedly connected, as at 17, with the intermediate door section A in such a manner as to swing inwardly of the car, and it is to be particularly noted that the upper door section C is of a width materially less than the width of the remaining door sections, and affords a means whereby the loading of a car may be facilitated, and whereby access may be had within the'car after the same is loaded, especially for the purpose of inspection.

As herein embodied, the upper door section C is mounted in an elevated position through the medium of the heads 18 carried by the shanks 19 disposed through the elongated slots 20 produced at predetermined points within the strapsS of the supporting member M, and coacting with the shanks 19 are the clamping'members 21 herein disclosed as conventional winged nuts. It will be self-evident that by loosening the winged nuts 21, the heads 18 may be readily moved out of engagement with the upper section C, and in practice I find it of especial advantage to have the heads 18, when in operative engagement with the upper door section C, to be disposed through the loop members 22 carried bythe inner face of the door section C, and whereby a more elfective connection is assured.

As herein disclosed, "the vertical jambs- 23 of the doorway or opening D areprovided at their lower QIldS With the vertically disposed strips 24 of a length less than the height or width of the lower door section B, and against which the inner face of the lower door section B is adapted to abut, and the jambs 23 are also provided at their upper portions with the strips 25 with which the outer faces of the intermediate door section A and upper door section B are adapted to contact, and the lower end of each of the strips 25 is provided with the socket 26, and the extension 27 of the locking strip 28 is adapted to be interposed between the lower end of the strips 25 and the sill S and with which contacts the outer faces of the intermediate door section A and the lower door section B, whereby it will be perceived that the door will beeffectively held within the doorway or opening D.

In addition to the coaction between the extension 27 and the socket 26, the strip 28 is maintained 'in applied position by the loop member 29 adapted to be received within the recess or pocket 30 produced in the jamb 23 adjacent the lower end thereof. The loop member 29 is maintained within its pocket or recess 30 through the medium of the latch member 31 provided with the elongated slot 32 through which is disposed the threaded bolt 33, carried by the lower door section B and with which coacts the clamping member 34 herein disclosed as a conventional winged nut.

VVhe-n the strip 28 has been. removed in order to permit the lower door section B to be opened, I prefer that the extension 27 of the strip 28vbe inserted within the upwardly disposed socket 35 afforded by the strip 25 at its outer edge and with the opposite end of the strip 28 in contact with the top or upper sill S of the'doorway or opening D, and to further maintain the strip 28 in its inoperative position, I provide the same in its end remote from the extension 27 with the slot 5st through which the headed member is adapted to be directed, said memher being capable of axial rotation in a manner and for a purpose which is be lieved to be self-evident.

- In ordervto prevent loss of the strip 28 I find it of advantage to suitably connect thereto a flexible member 56 of predeten,

as is tions' of the shanks 36 have coacting therewith the clamping members 39 herein disclosed as conventional winged nuts.

When the door proper has been moved to one side ofthe doorway or opening D, it is adapted to be received within a pocket P produced inthewall W, and in order to maintain the door within said pocket P, the angular extremities 3!? of the shanks 36' are'adapted to overlie a holding strip 'or beam 40 arranged within said pocket, and particularly illustrated in Figs. 2 and 4.

It is sometimes of advantage to support the door above the doorway of opening D, and for this purpose I have disposed transversely of the car body and secured to the roof R thereof and to the wall WV at a point adjacent the roof, the brackets 41 having their lower or longitudinal portions 42 arranged on inward and downward inclines,

' and slidably engaged with said portions 42 is the cross member 43 provided intermediate its length with the eyes 44 through which is disposed the intermediate portionof a flexible member 45, the extremities of which being secured. to the roof of a car, as indicated at 46, at apoint'above the inner ends of the horizontal or lower portions 42 of the bracket. lVhen the door is to be supported in its upward position, the lower door section B is swung upwardly whereupon the entire door structure is elevated or lifted and the cross member 43- moved therebe neath, as is indicated by dotted lines in Fig. 3. An end portion of a flexible member 47 is then engaged with theflexible member 45 at a point intermediate the eyes 44, preferably through the medium of the hook 48 carried by the flexible member 47, and the eye or ring 49 loosely mounted on the flexible member 45. The flexible member 47 is directed through the guide 50 carried by the side wall WV of the car body at a predeterminedpoint, and downwardly through theguides 51 and 52 carried by the adjacent jamb 23. Bypulling down upon the fiexi-' ble member 47 it will be perceived that the flexible member 45 will be disposed beneath the lifted door, whereby a further support for the door is afforded, and the cross member 43; is held against accidental ment from beneath the lifted door. The lower or opposite end of the flexible member 47 is provided with'a hook 53 adapted to coact with the member 47, which is preferably a chain, in such a manner as to hold the flexible member 45 inoperative adjustment.

From the foregoing description, it is thought to be obvious that a grain door constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and 1s particularly well adapted for use by reason of the convenience displacey door for the open ng in the side wall mounted at its upper end for swinging movement in a vertical plane, brackets supported by the-side wall and top wall above the opening of the side wall, said door .when in elevated-position being adapted to be positioned between the brackets, a cross member slidably engaged with the brackets and provided intermediate its length with longitudinally spaced eyes, a flexible member having its extremities secured to the roof of the car adjacent the inner ends of the brackets, the intermediate portion of said flexible member being threaded through the eyes of the cross member, and means coacting with the flexible member for holding the'same beneath the door when in an elevated position.

2. In combination with a side wall provided with anopening and a top wall, a door for the opening in the side wall mounted at its upper end for swinging movement in a vertical plane, brackets supported by the side wall and top wall above the opening of the side wall, said door when in elevated position being adapted to be positioned between the brackets, a cross member slidably engaged with'the brackets and provided intermediate its length .with, longitudinally spaced eyes, a flexible member having its extremities secured to. the roof of the car adjacent the'inner ends of the brackets, the intermediate portion of said flexible member being threaded through the eyes of the cross member, and means coacting with the flexible member for holding the same beneath the door when in an elevated position, said means also coacting with the flexible member for holding the cross member beneath the doorwhen elevated.

3. In combination with a side wall provided with an opening and a top wall, a

termediate its length with longitudinally &

spaced eyes, a flexible member having its extremities secured to the roof of the ear adjacent the inner ends of the brackets, theintermediate portion of said flexible member being threaded through the eyes of the cross member, means coacting with the flexible member for holding the same beneath the door when in an elevated position, a ring loosely engaged with the flexible member,

and means detachably engaged With said 10 ring for holding the flexible member beneath the door when in an elevated position.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses. FRANCIS M.. BRUBAKER.
